Supplementary Information

Annual U.S. emissions for the period of time from 1990 through 2023 are summarized and presented by sector, including source and sink categories. The inventory contains estimates of carbon dioxide (CO ² ), methane (CH ⁴ ), nitrous oxide (N ² O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulfur hexafluoride (SF ⁶ ), and nitrogen trifluoride (NF ³ ) emissions. The technical approach used in this report to estimate emissions and sinks for greenhouse gases is consistent with the methodologies recommended by the Intergovernmental Panel on Climate Change (IPCC) and reported in a format consistent with the Paris Agreement and United Nations Framework Convention on Climate Change (UNFCCC) reporting guidelines. The Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2023 is the latest in a series of annual, policy-neutral U.S. submissions to the UNFCCC. EPA requests recommendations for improving the overall quality of the inventory report to be finalized in April 2025, as well as subsequent annual inventory reports. Paul M.
